Annie Dillard's interaction with her readers about an experience of hers when she came across Weasels and was a part of them once, is 'Living like Weasels'.
Explanation:
Dillard talks about how humans have forgotten little things that give them happiness and start exploring unnecessary attributes that can cause destruction later in life.
Dillard explains about how Weasels have the capacity to act when necessary alone and refrain from what is not required at all, as they cannot think in several ways like humans do.
